Abstract
The program BABAYAGA is an event generator for QED processes at flavour factories, mainly intended for luminosity measurement of e+ e- colliders in the center of mass range 1-10 GeV. Recently, the pi+ pi- channel has been added as well. The relevant (photonic) radiative corrections are simulated by means of a Parton Shower in QED. The theoretical precision of the approach is estimated and some phenomenological results are discussed.
